Abu al-Qasim

936 – Abu al-Qasim was born in the city of El Zhara, six miles northwest of Córdoba, Spain. He descended from the Ansar Arab tribe who settled eariler in Spain.

963 – Abu Al-Qasim has been credited to be the first to describe ectopic pregnancy in 963, at that time a fatal affliction. Not always properly credited, Abu Al-Qasim’s Al-Tasrif described both what would later became known as "Kocher’s method" for treating a dislocated shoulder and "Walcher position" in obstetrics. Al-Tasrif described how to ligature blood vessels before Ambroise Paré, and was the first recorded book to document several dental devices and explain the hereditary nature of haemophilia.

1013 – Al-Qasim was a surgeon and specialized in curing disease by cauterization. He also invented several devices used during surgery, for the purpose of: inspection of the interior of the urethra, applying and removing foreign bodies from the throat, and inspection of the ear. He died in El-Zahra where he lived most of his life.
